46 THE ENTOMOLOGIST. 



dusking paid very little better. Night after night I spent in the 

 New Forest waiting in viiin for something to turn up. It was very 

 much the same here. It was not till I got to Lincolnshire, in the 

 latter part of July, that things began to appear on the wing at dusk, 

 but then not in any abundance, with the exception of Acidalia 

 bisetata, which really swarmed. I had never previously seen this 

 species in anything approaching the numbers which occurred. 

 Porthesia similis also flew freely. I only went out once in the late 

 autumn to look at the ivy, but though it appeared an ideal night not 

 a single moth could be seen. Altogether the past season has been in 

 the main distinctly disappointing. — J. E. Tabbat (Rev.); Fareham,

i\.DDiTioNAL Notes on the Rhopalocera of the Pas-de- 

 Calais AND the Somme. — As Mr. N. C. E. Miller surmised in his 

 article in the July ' Entomologist,' his observations were of great 

 interest to at least one other collector, whose duties for certain 

 periods were in the same localities. Where his notes agree with 

 mine I have not thought it worth while to record mine. With these 

 exceptions the following is a list of my observations for 1917 and 

 up to May, 1918 : Pajnlio machaon : The first brood worn in June, 

 the second brood common in August, 1917, at Albert. Some of the 

 ,^s were very dark. Colias hyale : Very common, both yellow and 

 white forms. Colias echisa: From July 3rd to September 24th, 



1917, at Albert, never common. Poltjgonia c-album: One hibernated 

 specimen, Avesnes-le-Comte, May 9th, 1917. Eugonia pohjcldoros : 

 St. Pol, 1917 ; Abbeville, 1918. JEuvanessa antiopa : One specimen, 

 Albert, August 14th, 1917. Araschnia levana: Locally common, 

 Flixecourt, 1918 ; ab. inorsa, Albert, 1917. Argynnis lathonia : One 

 example, Albert, August 10th, 1917. Brenthis enplirosyne : Flixecourt, 



1918. Melitcea cinxia ; Locally common, Flixecourt, 1918 ; 71/. 

 aurinia : Locally common, Flixecourt, 1918. Aphantopus hyper- 

 anthus : Albert, 1917. Zephyrus hetulcB : One freshly emerged 9 in 

 a garden in Albert, July 31st, 1917. Zephyrus quercus : One larva, 

 Avesnes-le-Comte, May, 1917, emerged June, 1917. Cyaniris 

 argiolus : St. Pol, 1917 ; Abbeville, 1918. Thanaos tages : Avesnes- 

 le-Comte, 1917 ; Abbeville, 1918. Adopcsa thaumas : Albert, 1917. 

 To recapitulate Mr. Miller noted the following six species which I 

 did not see; A. iris, L. sibylla, D. piaphia, A. aglaia, C. arcania 

 and G. rubi. My list adds the following ten species : C. echisa, 

 E. antiopa, A. lathonia, E. euphrosyne, M. aurinia, Z. betides and 

 quercus, C. argiolus, T. tages and .4. thaumas. P. napi were all 

 over the Somme area in 1917 in countless myriads, rising in clouds 

 from mud-patches. C. hyale and P. carclui were abundant, and 

 there appeared to be a succession of emergences. On June 28th, 

 1917, I saw a small dark Fritillary like Argynnis dia near Albert, but 

 I could not identify it. I searched in vain for L. sinapis, A. selene, 

 C. rubi, L. cor y don and bellargus in what appeared to be suitable 

 localities near Avesnes-le-Comte and Albert. — F. W. J. Jackson ;
